NOTE: This article is only applicable if you are using RStudio Workbench or RStudio Server (as opposed to using RStudio Desktop).
Run a Recent Browser Version
RStudio Workbench (previously RStudio Server Pro) makes use of a number of advanced web browser features and as a result benefits from running within more up-to-date browser versions. The following are the recommend minimum versions for various browsers:
Disable Pop-Up Blockers
There are a number of instances where RStudio workbench needs to show a new external popup window (e.g to display a PDF file). We therefore recommend that you disable pop-up blocking for the RStudio domain. Most browsers will prompt you regarding whether you want to enable popups for RStudio Workbench the first time one is blocked. Some browsers (such as Safari) may require you to globally enable and disable popups.
Disable Browser Spell Checking
If you are using a browser with built-in spell-checking, you may find it desirable to disable "Check Spelling While Typing" (available from the Edit menu) since many of the words you enter in the Source and Console will not be in the built-in dictionary and thus will show up with a red underline when entered.
